is a specification.

This application is a division of my application, Serial Number 536,660 filed June 6, 1910.

My invention relates to can body flanging machines.

The object of my invention is to provide a can body fianging machine of a simple, eflicient and durable construction, by meang anges cheaply flanged and by which the will be formed upon the ends of the can bodies uniformly and perfectly and also equally upon each end of the can body in cases where both ends of the can body are to be flanged.

The machine embodying my invention comprises in cotiperative combination, a movable carrier, preferably a continuously rotating carrier, a plurality of reciprocating flanging dies mounted on the carrier, an

each having a tapering head adapted to enter the can body and a surrounding limiting Wall or ring to limit the extent to which the flange may be turned on the can body, a plurality of can body holders or pockets on the carrier adapted to hold or support the can bodies between opposing fianging dies as the dies close upon the can body, and also adapted by engagement with the formed flange to strip or eject the can body from the flangin die as the flanging die withdraws, a de i-very chute and feeder for the can bodies adapted to automatically deliver the can bodies one by one into the pockets or holders of the carrier as the carrier rotates, a

discharge chute for the flanged can bodies and means, preferably stationary cams, for reciprocating the fianging dies as the carrier rotates.

My invention consists in the novel con struction of parts and devices and in.the novel combinations and sub-combinations of parts and devices herein shown and described and more particularly set forth in the claims.

part of this specification, Figure 1 is a side elevation of a continuous rotary can body flanging machine embod ing my invention. Fig. 2 s an end view. igs. 3, 4 and 5 are detail sections on lines 3-3, 4-4 and 5--5 of Fig. 1 respectively. Fig. 6 is. a detail horizontal section on line 6-6 of Fig. 3 and Fig. 7 is an enlarged detail sectional view, showing one pair of the flanging dies.

In the drawing, A represents the frame ofthe machine, which may be of any suitable construction adapted to give support to the other parts.

-M is a rotary carrier furnished with a series of can body holders or semi-circular pockets 6. Its shaft B is preferably continuously rotated from the driving shaft C through intermeshing gears C C. The can body carrier M is preferably formed of two separate disks secured to separate heads I) on the carrier shaft B which may be adjusted closer together or farther apart as may be required for operation upon can bodies of different sizes or lengths. The carrier disks B are preferably removably secured to the heads 6 by screws 1) so that carrier disks having can body holders or pockets 6 of different diameters or sizes may be changed, one for the other, to adapt the machine for operation upon can bodies of different diameters.

The carrier heads 5 are furnished each with a plurality of reel rocating can body Hanging dies D, each aving a tapering head or nose (2 to facilitate the entrance of the die within the end of the an body when the can body is bent or distorted out of shape, and each also. provided with a limiting shoulder or wall d against which the extreme outer edge as of the flange w of the can body X may enga 'e and thus limit the extent to which the filings will be turned upon each end of the can body as the flanging dies D enter the can body at opposite ends and approach each other. The limiting wall or shoulder d and the tapering head or nose d of the die are preferably formed in separate pieces from the main portion D of the die for convenience of manufacture. The limiting wall or ring 03? of the die preferably has an inwardly projecting flange or shoulder d fitting in a corresponding annular recess in the outer In the accompanying drawing forming face of the die D so that the tapering head ing d will serve te -hold all the parts assembled.

Each of the dies D is carried by aplate or holder D havingja, hub d fitting within the die 1) and carried by the reciprocatstem-or bar 1) which is mounted to slide'in the head I) of the carrier. The die stemfD 'is rovided at its outer end with which may engage a further stationary cam.

an" anti'f-fr'iction roller" 1) 'which engagesa stationary cam E on the frame of the'ma-' chine to reciprocate the die. The die stem or slide '1) is also providedwith a pin .D.

Ettdinsure-the proper withdrawal of the die-52s the. carrier rotates. The die stem or slide -D alsoehas an arm D against which a-springrE mounted in the head 1) acts to normally. ,withdraw the die after 'each'inward stroke of-the die.

' ;FL is the chuteor runway from which the can bodiesI -aredelivered one by one by theserve as means for stripping or ejecting'the' other of the dies as the dies Withdraw;

feeder G to the pockets of;th e carrier-B as the carrier rotates continuously feeder G preferably consists of a vibrating finger or arm lever g carrying, a roller g which is engaged by a cam g. -on the. carrier shaftB thus withdrawing 'the feeder so as to release the lowermost can body X in the feed chute The can body'feederlever g is preferably --furnished with a spring-g to. hold the same normally against the can 9 As the can bodycarriei' disks B B rotate n and move each holder in from the can body.

T e stationary cams E at each end of the machine are adjustably mounted upon-the frame, one of these cams preferably having a bolt and slot adjustmentEtE and screw E to adjust the cams closer together or farther apart as maybe required for operation upon can bodies of diiierent lengths, and the other cam being furnished with an adjusting drew E for accurately adjusting the approaching movement of the flanging dies toward each other to the length of hav ng a pivoted operating 6 of the carrier by a guard H secured to the: frame/of the machine &I1d' 'WhlCh encircles to be turned upon the can body.

If,- how'ever, it is desiredto formthe flanges uponf one end only of the can bodies, this may be readily done by sim ly substituting plain can bodysupporting v ispreferably interposed between one of the cams Band the a justor heads for the straight end of the can body to abut against' for the flanging dies at one end of theme-chine.
